  2. Agenda • Introductions • Discussion of Comments Received since June 18th Workshop • EVR System Certification Status • Proposed EVR Amendments • EVR Technology Review • Cost-Effective Analysis Update • Schedule

  3. See App. 1 of EVR Tech Review Report EVR Certification EVR Implementation EVR Emission Reductions EVR Cost Analysis EVR Comments Receivedbetween June 18th and July 31st

  4. Phase I Non-System-Specific Components Comment: Make System-Specific Phase I Components Non-System-Specific Response: No Why: 1) Need to define Phase I system 2) Components that may seem interchangeable have different requirements Example: Different torque settings for Phase I adaptors

  5. Phase I Non-System-Specific Components Testing Comment: Allow less than 180 day operational test for non-system-specific components to increase equipment availability Response: No Why: 1) Intent of non-system-specific is to allow use of components on multiple systems without full testing on EACH system 2) All components must successfully pass at least one operational test of at least 180 days

  6. EVR Phase II for Unihose and “Six-pack” Dispensers Comment: Can any EVR Phase II system be used on both unihose and six-pack dispensers? Response: Yes Why: The full EVR certification testing will be conducted using either unihose or six-pack dispensers. Field compatibility testing will be done using the alternate dispenser to allow the EVR Phase II system to be certified on both types of dispenser.

  7. EVR Phase II Systems with Conditional ISD Certification Comment: ARB proposes to allow limited term certification of systems with failures identified by ISD. The proposed limited term of 4 years for these certifications should be removed. Response: Yes, we will remove. Why: EVR certifications are already reviewed every four years. If deficiencies are identified, system cert will not be renewed.

  8. Use of EVR Nozzles on Pre-EVR Phase II Systems Comment: Will EVR nozzles be compatible with my existing dispensers? Response: Nozzles are expected to be compatible. However, if replacement nozzles are not compatible with the existing system, then a nozzle that was certified with the original system may continue to be used.

  9. Adding ORVR Compatibility to Pre-EVR Phase II Systems Comment: Can I add ORVR compatibility to my existing Phase II system so I can use until 2007? Response: Yes, if your system has demonstrated ORVR compatibility through ARB certification. Pre-EVR Phase II systems can seek Section 19 certification for ORVR compatibility until April 2005. Phase II systems obtaining Section 19 certification for ORVR compatibility may remain in use until April 2007.

  10. Upgrade of Pre-EVR Phase II Systems Comment: Will upgrading pre-EVR Phase II systems to be ORVR Compatible trigger EVR via major modification? Response: Not in most cases. Phase II major modifications are defined in D-200 as occurring when dispensers are replaced or 50% of buried vapor piping is added, replaced or removed.

  11. EVR for Districts in Attainment Areas? Comment: Districts in ozone attainment areas have vapor recovery to reduce benzene exposure.If EVR goals are ROG emission reductions, is EVR necessary for districts that meet the state ozone standard? Response: Will propose EVR exemption for existing installed systems in districts in ozone attainment, except for ORVR compatibility. New installations and facilities with major modifications must meet EVR standards.

  13. EVR Certified System Update • One certified EVR Phase I system • No certified EVR Phase II systems with ISD • No certified EVR Phase II systems without ISD

  14. EVR Phase I System Status • 19 applications received • 10 tests terminated • 3 systems under test • 3 systems waiting to start testing • 2 applications withdrawn • 1 system certified* * second system by end of Sept. 2002

  15. EVR Phase II System Status • 5 system applications • 0 test sites sealed • 0 systems currently on test

  16. Pre-EVR ORVR-Compatible Phase II System Status • 3 system applications • 1 test sites sealed • 1 system currently on test • 3 systems certified prior to EVR program (2 Healy and SaberVac)

  17. Agenda • Introductions • Discussion of Comments Received since June 18th Workshop • EVR System Certification Status • Proposed EVR Amendments • EVR Technology Review • Cost-Effective Analysis Update • Schedule

  18. Proposed EVR Amendments • Rigid piping definition • “Dripless” nozzle standard • Other CP-201 revisions • Test procedure changes • ISD-based maintenance during certification testing

  19. Rigid Piping • Already required in CP-201 • Proposed definition: any piping material with a bend radius that exceeds six feet as determined by TP-201.2G. • Similar to proposed UL standard for marina fueling systems

  20. “Dripless” nozzle standard • Currently “1 drop per refueling” • Only EVR standard determined not to be feasible in tech review • 3 drop average with 10 drop max proposed on June 18, 2002 • Current proposal: 3 drop average

  21. ISD Exemption Throughput • Currently 160,000 gallons/yr based on average throughput of GDF 1 facilities • Propose increase to 300,000 gallons/yr to include all facilities in GDF1 category

  22. Nozzle Standard Effective Dates • Change the effective dates from April 2001 to April 2003 for: • Liquid retention • Nozzle spitting • Spillage • Aligns with “dripless” nozzle and Phase II

  23. Processor HC rate Propose: “maximum hydrocarbon feedrate from to the processor shall not exceed 5.7 lbs/1000 gallons”

  24. Hand pump specifications • Deleted hand pump references from CP-201 • Spill container requirements regulated by State Water Resources Control Board

  25. Dispenser standard • Dispenser vapor piping for balance systems already designated as a non-system-specific component • Propose to remove “balance” to allow all dispenser vapor piping to be non-system-specific

  26. Daily high pressure • Clarify calculation in CP-201 • Intent: • Calculate the average pressure reading for each hour. • Identify the highest one-hour pressure average over a 24 hour period. This is the daily high pressure. • Compute rolling 30-day average of daily high pressures - may not exceed +1.5 inches water.

  27. Certification process changes • innovative system • throughput for sixpack dispenser • system-specific and non-system- specific • certify ISD by system type • ISD-based maintenance

  28. Innovative system • Intent was to allow flexibility for systems which emit much less than allowed by current standards • In practice - viewed as way to avoid compliance with some EVR requirements • Language to be modified to better reflect intent

  29. Test site throughput for sixpack dispensers • Unihose: Minimum throughput of 150,000 gal/month • Six-pack: Minimum throughput of 150,000 gal/month for one grade of gasoline

  30. System-Specific Components • Pass all tests on system that is or becomes certified. • Some components may then be certified on other systems after field compatibility, performance and efficiency tests. • Example: Phase I adaptors (if identical performance and installation).

  31. Non-System-Specific Components • Operational test of at least 180 days on a certified system. • May be certified on other certified systems after field compatibility and performance tests if meets all the system specifications. • Example: Phase II Hose.

  32. ISD Certification Process • ISD system type certification will be proposed in the EVR amendments

  33. ISD-based maintenance during certification testing • ISD benefit is immediate identification of system failures • We recognize that ISD will make it harder for Phase II systems to pass operational test • Provide limited repair of failures identified by ISD during certification

  34. ISD-Maintenance Criteria • No failure for 90 days • ISD-based maintenance included in maintenance manual • Maximum 5% of allowable downtime for ISD-detected failures • Manual field test failures are grounds for test termination

  35. ISD Certification Options • If ISD-detected failure occurs during certification: Phase II system certification will require use of ISD system • If no failures during certification: Phase II system may be certified for use both with and without ISD

  36. Revisions to Phase I Test Procedures

  37. Revisions to Phase II Test Procedures

  38. Proposed New Test Procedures

  39. TP-201.1 Phase I Efficiency • Current procedure assumes volume of vapor returned to cargo tank is same as volume of gallons dispensed • Revised procedure measure vapor volume directly using meter to improve accuracy

  40. Update of Other Phase I Test Procedures • TP-201.1B: Adaptor static torque • TP-201.1C:Drop tube/drain valve leakrate • TP-201.1D:Drop tube overfill prevention device leakrate • Improve equipment specifications • Clarify test procedure steps

  41. TP-201.2B Component leakrates • Current procedure for P/V valve leak measurement uses rotameters • Revised procedure allows option for mass flow controller to improve accuracy • Removed TP-201.2B Appendix to create TP-201.1E

  42. TP-201.2D Dripless nozzle • 15 drops/ml to be changed to 20 drops/ml to be consistent with spillage procedure • Modifications suggested to improve method consistency and conduct fueling similar to average customer

  43. Change time nozzle in vehicle from 10 to 5 sec

  44. Nozzle Spout Horizontal, Not Upside Down for Drip Count Adopted TP-201.2D Proposed TP-201.2D

  45. TP-201.2F Pressure-related fugitives • Current procedure has missing equations • Change time for pressure decay from 20 minutes to 5 minutes

  46. TP-201.2J: Balance component pressure drop • New procedure • Bench test to determine pressure drop for balance components

  47. TP-201.7: Continuous pressure monitoring • New procedure • Describes equipment and procedure for pressure monitoring required for operational tests during certification
